The important things about weight control are continued motivation and maintenance of good eating habits.
You've done extremely well and need to enjoy festivities without losing motivation.
OK. I'm saying this as making it public will help with motivation. My diet is pretty good most of the time. I eat avocado, one or two slices of soughdough a day, brown rice, sweet potato, fish - eg mackerel or salmon, yoghurt, berries, a banana, peanut butter/rice cake etc. I'm like one of those motivation fitness blogs without the picture of a person doing yoga in the background.
I don't eat crisps, chocolate, calorific puddings, chips, soda - all the usual things that people cut out when they start a diet. I don't mind these foods but they are not part of my diet, I don't crave them and rarely if ever, have them.
My big pitfalls are beers, coffee and portion control after I've been exercising. I've trained for marathons and gained weight! I get into the habit of having two or three beers a night for a week and then stop for a week and then start again. No rhyme or reason, I just like beer. This is a habit I need to get out of after Christmas. When I go out (not very often) and have a binge I find it really hard to shift the subsequent weight gain.
I've got polycystic ovaries which makes it even more of a pain to lose weight.
I cycle everywhere, gym three or four times a week (bench press, squats, deadlift), wattbike sessions a couple of times a week. I'm really challenging myself now and trying to hit targets.
My body might be annoying but I'm going to drink more water (rather than coffee) and battle through the knawing hunger and try to sort it out in January!
